What is going on with this Caddx Vista?

Yet another reason to #hate on #digital #fpv. Can someone with a knowledge of what this might be comment? Running the #caddx #vista. On this #tuning flight snippit #video is all messed up, corrects itself, goes bad again, then corrects itself for the rest of the flight. On a subsequent flight the video starts bad, corrects itself, then stays bad. After that it starts bad and stays bad. Swapped the coaxial cable with the same results. Swapped #vtx #antenna same results. Really do not want to buy another camera.
